I wish I knew the answer to that question
I'm assuming he will start to perform better as the season progresses, but there is a strong possibility things don't work out in Dallas and he ends up only seeing backup minutes nightly.
I'm currently debating who I should drop him for. I'm already stacked at SF with Lebron and Danny Granger, so I don't NEED Odom; I'm just hesitant to drop him only to have him get his act together and end up being a beast for someone else. Essentially I don't even want him on my team, I just don't want anyone else to have him haha.
If you don't have any specific team needs you could just drop him for Ron Artest, who is another player like Odom that gives you a bit of everything (my only real team need right now is 3pt, but he is still in my top 5 replacement considerations due to everything he can produce)
